"At least in the last year-plus, lefties have taken some better swings against [Morrow]," manager John Farrell said.

Entering Saturday, lefties have hit .283/.353/.543 against Morrow this season, which is significantly better than the .200/.273/.333 mark right-handers have compiled. In 2012, it was much of the same, as lefties had an OPS .300 points higher than righties vs. the hard-throwing Morrow.
